Instructions are also included on the side of each injector if you forget how to use it or someone else needs to give you the injection.

Positioning and resuscitation

Someone experiencing anaphylaxis should be placed in a comfortable position.

Most people should lie flat.

Pregnant women should lie on their left side to avoid putting too much pressure on the large vein that leads to the heart.

People having trouble breathing should sit up to help make breathing easier.

People who are unconscious should be placed in the recovery position to ensure the airway remains open and clear – place them on their side, making sure they're supported by one leg and one arm, and open their airway by lifting their chin.

Avoid a sudden change to an upright posture such as standing or sitting up – this can cause a dangerous fall in blood pressure.
